Type: 2. Preservation — A carpenter, sometimes rendered as cafner, refers to a type of woodlouse (see Image 1), which lives most commonly in decaying wood or under rocks (see DNE, s.v. "carpenter"). Other popular names for this species include: woodlouse, slater, pillbug, sowbug (see the 1981 quotation). The term carpenter is likely a preservation from British English (see EDD, s.v. "carpenter" (2) and "cafender" (2)).
